An idealized current quadrupole source in linearized gravity rotates
in a right-handed sense about the z-axis, emitting gravitational
waves. This video shows the structure of vortex lines associated with
this radiation process. The nearly-radial gray lines have negligible
vorticity, and so are not directly related to gravitational waves.
The blue and red curves have significant positive and negative
vorticity (respectively), and are drawn into twisted spirals by the
rotation of the source. It is descrbed in our work, Visualizing
Spacetime Curvature via Frame-Drag Vortexes and Tidal Tendexes
